I don't think the post is about "The Feels of Gen 1." The episode this is from is where Ash gets trapped in an ice cave and he tries to keep all his pokemon in the balls but they end up all getting out and all start hugging ash to keep him warm. The feeling is not "DAE GEN 1" but "Look how sweet those pokemon are! <3"

Actually this episode was showed to America AFTER Charizard evolved, but was created before then. How? This episode and a few others with them have Charmander when he did not evolve, although he did a few episodes earlier. This is because they made this episode before Charmander evolved. It was made for a Christmas special (yes, they are Japaneese, but they had hearts too, you know... After WWII). They just never got around to showing it during that time, so, a few months later, they showed this episode. They couldn't just throw away an episode! They need to feast off of our tears!
